Policy routing (ip rule) on the real server, keyed on local source
192.168.13.0/24, e.g.
ip route add 192.168.13.0/24 table 1234
ip route add default via 192.168.13.254 table 1234
ip rule add from 192.168.13.0/24 table 1234
If you can make it so, best also separate the LVS traffic in a
different VLAN. You still need that policy routing, but the resulting
setup is simpler to debug and analyze and has some operational
advantages that I won't go into now :)
best regards
